For her PhD thesis, Bergström conducted a group randomized trial concerning psychoprophylaxis during child birth, evaluating the use by both the mothers and the fathers.
[1] In 2011, Bergström started to work on the Elvis project at the Center for Health Equity Studies, a joint venture of Stockholm University and the Karolinska Institute.
This project is a longitudinal research study that follows the health and well-being of children after their parents have divorced or separated.
With Sweden as one of the early adopters of shared parenting, the project is unique in its ability to evaluate and compare long-term effects of different custody arrangements.
[5] Bergström's research has received international media attention by for example Time Magazine,[6] Yahoo Parenting,[7] Radio Canada,[8] and Science Daily.
